To aZZ zoltom' it may concern: p link fit 'Beit known that I, OLIVER II.ROBERTSON, of 11 V b otForestville, in the county of Hartford and telosethe other- 5 new and useful Improvements in Nut-Oraekconnect thelink and jaw securely. The link ers, of which the following is afull,clear, and is preferably made of a single piece of metal exactdescription, whereby any one skilled in formed to shape, with thecentral portion out the art can make and use the same away, leaving apivot g, and having at the '60 to device for cracking nuts that can beheld in are all preferably made of cast metal formed the hand of theuser and operated with power to the desired shape and of suchproportions suflicient to crack the strongestnut that may as to bereadily assembled. It is desirable be inserted between the jaws that thejaws should be normally held apart,

To this end my invention consists in the deas by means of a spring, andthis is effected I5 tails of the several parts making up the nut in theform shown by means ofa spiral spring and pointed out in t 0 claims.against a shoulder or partition 7L3, formed on teferring tothe drawings,Figure 1 is a dethejaw 71, the spring being always held under 20 tailside view of the nut-cracker, showing in compression.
